So I’m not too sure where to start here. I have had issues in the past with contaminated fluid , usually water . My tractor (m100x) is kept inside when it’s not being used . I changed the hydraulic pump on it as well as changing my filters and I changed my hydraulic oil 2x to ensure there was no debris or any water . I just ran my tractor to feed and when I went to check my oil when it shut it down it was a bit milky. Am I not working my machine hard enough to make the moisture disappear ? Where’ should I be checking for water entry points on my machine ? Thanks for the help .

You only changed one hydraulic pump?
Which one?

Have you been changing both filters on it?

When you changed the pump did you inspect all of the suction lines and fittings?

You probably done that already, but every implement you used would have water in the oil too, so you have to remove that too. Otherwise as soon as you connect it to the tractor hydraulics some water is back in the hydraulic oil.

And where is the water coming in the first place?

Do you keep it in a heated building? If so going from a warm building to cold outside over and over again will create more condensation inside the tractor.
